   1.                                                   Given the significance 
of your research and development (R&D) expenses for the periods
                                                        presented, please 
revise your future disclosures to quantify such expenses by product
                                                        candidate and provide a 
detailed analysis of the changes therein. To the extent you are
                                                        unable to track such 
costs at that level, revise to disclose that fact and identify the reasons
                                                        why. For all amounts 
that are not allocated by product candidate, provide a breakdown by
                                                        type or nature of 
expense, such that the total reconciles to the research and development
                                                        line item on the face 
of your statement of operations.

2.       You disclose that you did not identify any change in your internal 
control over financial
         reporting that occurred during your latest fiscal quarter that has 
materially affected, or is
         reasonably likely to materially affect, your internal control over 
financial reporting, but
         that because your "evaluation is ongoing and because of its ongoing 
nature, there can be
         no assurance that we will not identify any change that would 
materially affect, or be
         reasonably likely to materially affect, our internal control over 
financial reporting." We
         note this same qualifying language is included in the Form 10-Q for 
the quarter ended
         March 31, 2023. Please revise your future disclosures to comply with 
the the requirements
         of Item 308(c) of Regulation S-K by providing a clear positive or 
negative conclusion that
         omits similar such qualifying language and to clearly disclose any 
material changes
         identified.
       In closing, we remind you that the company and its management are 
responsible for the
accuracy and adequacy of their disclosures, notwithstanding any review, 
comments, action or
absence of action by the staff.
